Itchy within vaginal area pretty normal, I had it for my #1 throughout pregnancy and this is due to hormonal changes, therefore the discharge release makes our vulva/vaginal area get pretty itchy. However, if this is a concern you may wish to speak with your gynae.
I prepare a lining pad for daily use, change it when it stains. It can be annoying esp when overseas. Then if possible and at convenient place, will wash with clean water and dap it dry at the vaginal area.
